SPECIFICATION forming part of Letters Patent No. 680,990, dated August 20, 1901.

Application filed April 27, 1901- To all whom it may concern.-

Be it known that I, J Anne E. COMPTON, a subject of the King of England, residing at Lynn, in the county of Essex and Qtate of Massachusetts, have invented new and useful Improvements in Rotary Brushes,of which the following is a specification.

The object of this invention is to produce a rotary brush for cleansing castings and the like, which shall be very durable and eflicient in operationand in which the portions which do the actual work of cleansing may be readily renewed when worn.

The invention consists of a rotary brush comprising a holder and a series of U -shaped cleansing-wires attached to the periphery of i The invention further consists in the specific means whereby said cleansing-wires are attached to said holder.

The invention still further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a front elevation of my improved rotary brush. Fig. 2 is a detail section taken on line 2 2, Fig. 1. Fig. 3 is an enlarged detail section taken on line 3 3, Fig. 1. Fig. at is a detail sidefelevation, and Fig. 5 an end elevation, of one of the wire-clamp plates. Fig. 6 is a perspectiveview of one of the cleansing-wires. Fig. 6 is a transverse section taken on line 6 6, Fig. 3.

. Like numerals refer to like parts throughout the several views of the drawings.

In the drawings,:7 is the hub of the brush,

semicircular flanges 9 upon the periphery The flanges 9 extend at right angles U-shaped cleansing-wires 10. Said U -shaped cleansing-wires are arranged in bunches, sepagainst the flanges 9 by clamp-plates 11, secured thereto bya screw 12. The clampplates 11 each consist of a semi-annular ring, provided upon the periphery thereof with semicircular grooves l3,which prevent the different bunches of wires from moving lengthther securely hold the cleansing-wires, I pro- Serial No. 5 7 66 7. (Nomodeld vide a leather packing 15 between the flange 5 5 9 and the clamp-plate 11. It will be seen that the plate 8, with the hub 7 and flanges 9 thereon, constitute a holder for the U -shaped cleansing-wires 10, said U-shaped cleansing wires being clamped midway of the ends by the plates 11 to said holder.

The operation of the device is as follows: The hub 7 of the brush is fastened to a rotary shaft and the casting or other article to be cleansed is held against the rapidly-rotating cleansing 'wires 10, which remove all dirt and sand or rust from the surface of said casting in a very short time and in a very thorough manner.

When the wires become Worn or broken,

they may be removed and new ones substituted by unscrewing the screw 12 and removing the clamp-plate 11.

I prefer to use a flat wire similar to that shown in Fig. 6; but it is evident that a cylindrical wire may be used without departing from the spirit of my invention and also that said wires may be attached to the periphery of a rotating holder in a variety of ways without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a rotary brush, a holder, a series of semicircular flanges upon the periphery thereof, a series of U-shaped wires, a series of clamp-plates eachof said plates consisting of a semi-annular ringwith semicircular grooves in the periphery thereof, and means for attaching said clamp-plates to said holder, substantially as described.

2. In a rotary brush, a holder, a series of semicircular flanges upon the periphery thereof, a series of U-shaped wires, a series of clamp-plates, each of said plates consisting of a semi annular ring with semicircular grooves in the periphery thereof, means for attaching said clamp-plates to said holder, and a packing of soft material interposed between said U-shaped wires and said flanges, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

JAMES E. COMPTON.
